MANUFACTURE OF ORNAMENTAL GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 331,824, dated December8, 1885.

Application filed September 21, 1885. Serial No. 177,662. (Specimens.)

To all wwnt t may concern:

Be it known that we, DANIEL C. RIPLEY, AUGUSTUS H. HEIsnY,and GEORGE B.SWIFT, of Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in theManufacture of Ornamental Glassware; and we do hereby declare thefollowing to be a full, clear, and exact description thereof.

It has been customary in the manufacture of parti-colored glassware tocover the surface of the clear-glass article with a thinlayer of coloredglass by the process known to the glass trade as flashing and then tocut the desired figure or pattern into the surface of the articlethrough and below the colored surfacelayer. The product of this processis one of the most expensive kind of glassware, for the reason that theoperations of flashing and cutting are both very expensive. Consequentlythis glassware is in but limited use, and is practically beyond thereach of persons of limited means.

The object of our invention is the production of an article of similarcharacter and like appearance at a greatly reduced cost.

To enable others skilled in the art to make use of our invention, wewill now describe it, reference being had to the accompanying drawings,in which- Figure l is a bottom view of a glass dish produced by ourimproved method, and Fig. 2 is a side view of the same.

Like letters of referenceindicate like parts.

The dish a is pressed in asuitable mold, the inner face of which is cutwith the design or pattern, which will produce the design which appearson the surface of the article, consisting of a series of grooves, b,crossing each other at various angles, in imitation of a patternproduced by the operation oiglass-cutting, and such as will leave aseries of raised surfaces, c, of the shape shown, or of other shapes,

depending on the particular pattern selected. The raised or elevatedsurfaces are then coated with a suitable coloring-matteror paint,leaving the grooves or depressed portions clear, and then the article isplaced in a suitable oven or furnace, and the coloring-matter is bakedin the manner practiced in baking decorated plaques.

vThe pressing operation, if carefully conducted with clear sharp-cutmolds, will produce articles so nearly resembling cut ware that thedifference can only be detected by an expert, and with a little care theapplication and baking-on of the color can be so perfectly done as to beindistinguishable by inspection of the article alone from flashed glass.

The cost of the whole operation is little, if E any, greater than thatof the ilashing operation, and it produces a beautiful and salablearticle, which t-he manufacturer is able to sell at a price low enoughto put it within the reach of persons of limited means who are unable toafford the cut ware before referred IVhat we claim as our invention, anddesire to secure by Letters Patent, is

The method of making ornamental glassware, which consists in pressing aglass arti cle with raised and depressed surfaces, in imitation ofcut-glass patterns, painting the raised surfaces, and then baking in thecolor on the same, substantially as and for the purposes described.

In testimony whereof we have hereunto set our hands this 2d day ofSeptember, A. D. 1885.
